I have (2) Billy Goat vacs with Tecumseh 5HP engines. I'm thinking between the two of them I have enough parts to make one good complete unit. One of the engines is a TVS-120 (SN 8187A) and the other is a TVM-125 (SN 71800). Question is...if I pull the carb from the TVM-125, will it work on the TVS-120? Anyone have any support docs or experience? Thanks.
